HULLEBrCOTTON-GIN ATTACHMENT.

Application filed January 21,1915. serial No. 3,533.

T 0 all whom it may concern Be it known that I, JAMES E. TAYLOR, acitizen of the United States, residing at McKinney, in the county ofCollin and State of Texas, have invented certain new and usefulImprovements in HullenCotton- Gin Attachments, of which the following isa specification.

My invention has relation to'that class or type of cotton gins known ashuller gins wherein the cotton, imperfectly separated from its hulls, isintroduced into a chamber or proper receptacle and subjected to theaction of a huller roll prior to its presentation to the saws of the ginfor removal by saidsaws to the roll boX of the gin; and

in such connection it relates more particularly to the construction andarrangement of the huller. chamber whereby the base of said chamberadjacent to the teeth of the huller roll is closed to prevent cotton inthe chamber from passing out therefrom, the closure for the base of thechamber being of a pilous nature and snugly fitting the teeth andcylinder of the huller'roll, without preventing or obstructing theproper operation of said roll. a

The principal objects of my present invention are first, to provide inahuller gin,

a closure for the base of the huller chamber, said closure being ofsimple construction and of ready adjustment and when operativelyassembled in the gin, serving to prevent thecotton from passing out ofthe base of the huller chamber without interfering. with the properoperation of the huller roll; and second; to provide, in a huller ginwherein the huller roll operatively rotates in the base of the hullerchamber, a closure for said base comprising a pilous strip or stripsprojecting in the path of the teeth of the huller roll'and ar.-.

as are necessary to understand m inven Specification of Letters Patent.Pa,tented 14:, 1916.

tion-being shown. Fig. 2 is horizontal sectional view of the same, thesection being taken on llne a-a ofFig. 1. Fig. 3 is an enlarged detailview in longitudinal section ,of the huller roll, the pilous closure andaux liary parts. Fig. 4 is a view similar to Fig. 3' but illustrating anaddition to the parts therein shown, a means for adjusting each pilousstrip in its support. Fig. 5 is an underneath plan view of Fig. 2. Fig.6 is a view similar to Fig. 4 but illustrating a modified form of meansfor ad justing the pilous strips. Fig. 7 is an underneath plan view ofFig. 6, and Fig. 8 is a cross sectional view taken on line w'm of Fig.7. V i

Referring to the dra'wingsl I represents the huller'chamber, 2 therollchamber or box, 8'the gin saws, 4 the brushes and 5 the huller' rollof a cotton gin, all constructed and arranged to operatein the usual'well known manner. Adjacent to the saws 3 in the spaces which separatethe saws on the saw shaft 3 are arranged the usual ribs through whichcotton from the roll box is pulled to cleanse it from seed prior to itspassage on the saws to the lint removing brushesfl. a I Referring nowto'the hulling H and the chamber wherein the hulling roll 5 is adaptedto'revolve it will be seen tha t mechanism the base 1 of said chamberis'jnormally open, beinghowever partly closed by the roll- 5, and anadjustable breast or'partiti'on 6 projecting from the front wall ofchamber 1 angularly toward the surface of roll 5; This partition 6 ishinged at 71 and a bolt 8 is pivotally secured at one end tothe'partition 6. and'projects' through the wall or 7 frame, 9 belowthe.huller chamber 1. A thumb, nut 10 or other suitable, means, threaded onthe projecting end of :bolt'8' serves to change the angularrelationshipof breast or partition .6 to the front of chamber 1. The lower free endofthe partition or breast 6 is provided with a channeled metallic strip11 in which is tightly clamped arowor strip 12 of pilous material suchas brlstles. A convenient means'for clamping the metallic strip to-o thebristles 12 as wellas securing said'strip to the partition 6 consists ofscrews 13 passing through the strip 11', pil'o'usmaterial 12- and intothe partition 6 as clearly shown in Fig. 3. Therow 19."

of pilous material projectsfromthe partition 6 directly into the path ofthe teeth 5 and radially of the hullerroll 5 and preferably wipes uponthe cylinder from which said. teeth 5 project. It follows therefore that.the portion of. the base of.

the huller chamber between the huller roll 5 and partition 6 is closedor screened by a row of pilous material 12 through which the teeth 5 ofthe roll 5 may pass without vided with a series of teeth 15 adjacent tothe teeth 5 of roll 5 and arranged to perniit the teeth 5 to traversesaid teeth 15. In this instance the pilous material 12 serves to closethe apertures between teeth 15 of partition 6 being arranged below saidpartition 6 as well as to close the space between the edge of saidpartition and the cylinder of the huller roll 5. In addition to thestrip 12 of pilous material there is arranged preferably diametricallyopposite said strip 12, a second strip 17 of.pilous material secured toand supported'by the frame 16 adjacent to ribs 16. The pilous fringe oredge of this strip 17 as arranged in Fig. 3 projects tangentially of thehuller roll 5 and serves as a closure for thebase of chamber 1 betweensaid huller roll 5 and the rib carrying frame 16 In the formsillustrated inFigs. 4: to 8 inclusive the strip 17 is arranged almostradially of the huller roll 5.

In the form of my invention illustrated in F igs. at to 8 both pilousstrips 12 and 17 are provided with means for adjustment to ward or awayfrom. the roll 5 irrespective of the adjustment of the parts by whichsaid closures 12 and 17 arev supported or carried. l/Vhile of coursestrip 12in Fig. 3 may be adjusted by the operation of the bolt 8 whichserves primarily "to adjust the parti-' tion 6 still it is desirablethat eachstrip 12 or 17 have an independent adjustment.

In the form of adjustment shown in Figs. 4: and 5, the metal strip 11which carries and holds the pilous layer 12 and the similar strip 11.for layer 17 are each slotted transversely as illustrated at 18 and 19in Fig.

5. Headed screws 20 and21 passing throughrespectively slots 18 andl9rserve to secure the metal. strips 11 respectively to the parstition-G and to the frame 16 in such a manner that the strips 11 may beshifted. forward toward roll 5 or ZtWHYfI'OHTttllG same as oocasiondemands. In other words the strips 11 are in slotted engagement throughscrews 20 and 21 with. their supporting parts. .In

Figs. 5 to 8 inclusive, a modified form of adjustment of strips 11 isshown. The strip 11 of layer12 carries at either end of the strip athreaded'bolt 22 passing through a bracket 23 depending from the underside of partition 6. The thumb nut 24 on each bolt 23 serves to advanceor retract the bolt in said bracket 23 to thereby slide the strip 11in'the end. brackets 25 of the partition 6.. The strip 11 carrying thelayer 17 is confined so as to slide on its supporting part 16 by the endbrackets 26. The underface of the metallic strip 11 carries at each enda rack 27 and in each rack 27 a pinion 28 meshes. The pinions 28 areeach supported in bearings 29 arranged at either end of the frame 16"and a knurled nut 30 in the shaft. carrying the pinion 28 serves tooperate said pinion to thereby through each rack 27,

slide the strip on its support 16.

Having thus described the nature and ob jects of my invention what Iclaim as new and desire to secure by Letters Patent, 1s-

1. In combination with a huller chamber,

an inclined partition in the base of said chamber and a strip of fpilousmaterial carried by the lower free end of said partition, of a hullerroll and its teeth arranged in the base of said chamber, said teethtrav' ersing the pilous material of the partition and means'for adustingthe partition and strip of pilous material toward or away from theroll.

In combination" with a hull-er chamber, huller ribs, a huller roll andits teeth rotating in the base of said chamber, of a 'pilous closure forsaid base comprising a strip of pilous material projecting into the path:of

the teeth cfthe huller roll and arranged radially of said roll, and asecond strip of pilous material projecting from below the huller ribsinto the path-0f the teeth of the huller roll and arranged tangentiallyto-the roll and approximately diametrically of the radially projectingstrip.

3. In combination with a huller chamber,

huller ribs, a huller roll and its teeth rotat-- ing in the base of saidhuller chamber, of a pilous closure for said base, said. closurecomprising a plurality of strips of pilous material pro ectingrespectively from either side of the outlet from said chamber andtraversed by the. teeth of the huller roll,

and means for adjusting one of said strips.

toward or away from the huller roll.
